telephone line cord and the telephone wall jack (see the following page). The  
filter prevents noise and caller ID problems caused by DSL interference. Please  
contact your DSL service provider for more information about DSL filters.  
Your product may be shipped with a protective sticker covering the handset or  
telephone base display - remove it before use.

Caller ID  
About caller ID  
This product supports caller ID services offered by most  
telephone service providers. Depending on your service  
subscription, you might see the caller’s number, or the caller’s  
name and number from the telephone company after the first  
or second ring. Caller ID allows you to see the name, number,  
date, and time of calls.

Information about caller ID with call waiting  
Caller ID with call waiting lets you see the name and  
telephone number of the caller before answering the  
telephone, even while on another call.  
It might be necessary to change your telephone service to  
use this feature. Contact your telephone company if:  
• You have both caller ID and call waiting, but as separate  
services (you might need to combine these services).  
• You have only caller ID service, or only call waiting service.  
• You don’t subscribe to caller ID or call waiting services.  
There are fees for caller ID services. In addition, services may  
not be available in all areas.  
This product can provide information only if both you and the caller are in  
areas offering caller ID service and if both telephone companies use compatible  
equipment. The time and date are from the telephone company along with the  
call information.  
Caller ID information might not be available for every incoming call. Callers  
may intentionally block their names and/or telephone numbers. To view call  
log entries with numbers between 16 and 23 digits, you must save the entry to  
the directory (see page 34)  
NOTE: You can use this product with regular caller ID service, or you can use this product’s  
other features without subscribing to caller ID or combined caller ID with call waiting service.

Caller ID  
Caller ID history  
How the caller ID history (call log) works  
The telephone stores caller ID information about the last 50  
incoming calls in the telephone base. Entries are stored in  
reverse chronological order. The phone deletes the oldest  
entry when the log is full to make room for new calls. This  
information is common to all handsets, so changes made using  
any handset are reflected in all other handsets. If you answer a  
call before the information appears on the screen, it does not  
show in the caller ID history.  
CHRISTINE SMITH  
888-722-7702  
NEW  
10:01AM  
11/23  
Review the caller ID history to find out who called, to easily  
return the call, or to copy the caller’s name and number into  
your directory.  
XX MISSED CALL(S) appears if there are new call log entries  
(including missed and unreviewed calls). CALL LOG EMPTY  
appears if there are no records in the call log.  
NOTES:  
1. Only one handset can review the caller ID history at a time. If another handset tries to enter the  
directory or caller ID history, it shows NOT AVAILABLE AT THIS TIME.  
2. Each entry can have up to 24 digits for the phone number and 15 characters for the name. If  
the phone number has more than 15 digits, only the last 15 digits appear. For call log entries  
with numbers between 16 and 23 digits, in order to view the entire number, you must save  
the entry to the directory (see page 34). If the phone number has more than 24 digits, it is not  
saved or shown in the call log.  
3. The caller ID information might not be available for every incoming call. The callers might  
intentionally block their names and/or telephone numbers.

If the incoming telephone number exactly matches a telephone

NOTE: The number you see on your caller ID is in the format from the  
phone company. The phone company usually delivers ten-digit phone  
numbers (area code plus phone number). If the telephone number of the  
caller does not exactly match a number in your directory, the name  
appears the same from the phone company. For example, if the phone  
company includes the area code and the directory number does not, the  
name is the one which the phone company sends.

Maintenance  
Taking care of your telephone  
Your cordless telephone contains sophisticated electronic parts, so you must treat it with care.  
Avoid rough treatment.  
Place the handset down gently.  
Save the original packing materials to protect your telephone if you ever need to ship it.  
Avoid water  
You can damage your telephone if it gets wet. Do not use the handset in the rain, or handle it  
with wet hands. Do not install the telephone base near a sink, bathtub or shower.  
Electrical storms  
Electrical storms can sometimes cause power surges harmful to electronic equipment. For your  
own safety, take caution when using electric appliances during storms.  
Cleaning your telephone  
Your telephone has a durable plastic casing that should retain its luster for many years. Clean it  
only with a soft cloth slightly dampened with water or a mild soap.  
Do not use excess water or cleaning solvents of any kind.  
Remember that electrical appliances can cause serious injury if used when you are wet or standing  
in water. If the telephone base should fall into water, DO NOT RETRIEVE IT UNTIL YOU UNPLUG  
THE POWER CORD AND TELEPHONE LINE CORDS FROM THE WALL. Then pull the unit out by the  
unplugged cords.

Appendix F  
Important safety information  
Especially about cordless telephones  
Privacy: The same features that make a cordless telephone convenient create some limitations.  
Telephone calls are transmitted between the telephone base and the handset by radio waves,  
so there is a possibility that your cordless telephone conversations could be intercepted by  
radio receiving equipment within range of the cordless handset. For this reason, you should not  
think of cordless telephone conversations as being as private as those on corded telephones.  
Electrical power: The telephone base of this cordless telephone must be connected to a working  
electrical outlet which is not controlled by a wall switch. Calls cannot be made from the  
handset if the telephone base is unplugged, switched off or if the electrical power is interrupted.  
Potential TV interference: Some cordless telephones operate at frequencies that may cause  
interference to TVs and VCRs. To minimize or prevent such interference, do not place the  
telephone base of the cordless telephone near or on top of a TV or VCR. If interference is  
experienced, moving the cordless telephone farther away from the TV or VCR will often reduce  
or eliminate the interference.  
Rechargeable batteries: This product contains nickel-metal hydride rechargeable batteries.  
Exercise care in handling batteries in order not to create a short circuit with conductive material  
such as rings, bracelets, and keys. The battery or conductor may overheat and cause harm.  
Observe proper polarity between the battery and the battery charger.  
Nickel-metal hydride rechargeable batteries: Dispose of these batteries in a safe manner. Do not  
burn or puncture. Like other batteries of this type, if burned or punctured, they could release  
caustic material which could cause injury.  
The RBRC™ Seal means that the manufacturer is voluntarily participating in an  
industry program to collect and recycle nickel-metal hydride rechargeable batteries  
when taken out of service within the United States. These batteries may be taken  
to a participating local retailer of replacement batteries or recycling center. Or you  
may call 1 (800) 8-BATTERY for locations accepting spent Ni-MH batteries.  
Precautions for users of implanted cardiac pacemakers  
Cardiac pacemakers (applies only to digital cordless telephones):  
Wireless Technology Research, LLC (WTR), an independent research entity, led a multidisciplinary  
evaluation of the interference between portable wireless telephones and implanted cardiac  
pacemakers. Supported by the U.S. Food and Drug Administration, WTR recommends to physicians  
that:  
Pacemaker patients  
Should keep wireless telephones at least six inches from the pacemaker.  
Should NOT place wireless telephones directly over the pacemaker, such as in a breast pocket,  
when it is turned ON.  
Should use the wireless telephone at the ear opposite the pacemaker.  
WTR’s evaluation did not identify any risk to bystanders with pacemakers from other persons using  
wireless telephones.

(“PRODUCT”) are free from defects in material and workmanship, pursuant to the following terms  
and conditions, when installed and used normally and in accordance with the PRODUCT operating  
instructions. This limited warranty extends only to the CONSUMER for products purchased and used  
in the United States of America and Canada.  
2. What will be done if the PRODUCT is not free from defects in materials and workmanship  
during the limited warranty period (“materially defective PRODUCT”)?  
During the limited warranty period, the manufacturer’s authorized service representative will repair  
or replace at the manufacturer’s option, without charge, a materially defective PRODUCT. If the

manufacturer chooses to replace the PRODUCT, they may replace it with a new or refurbished  
PRODUCT of the same or similar design. The manufacturer will retain defective parts, modules, or  
equipment. Repair or replacement of the PRODUCT, at the manufacturer’s option, is your exclusive  
remedy. The manufacturer will return repaired or replacement products to you in working condition.  
You should expect the repair or replacement to take approximately 30 days.  
3. How long is the limited warranty period?  
The limited warranty period for the PRODUCT extends for ONE (1) YEAR from the date of purchase.  
If the manufacturer repairs or replaces a materially defective PRODUCT under the terms of this  
limited warranty, this limited warranty also applies to repaired or replacement PRODUCT for a  
period of either (a) 90 days from the date the repaired or replacement PRODUCT is shipped to you  
or (b) the time remaining on the original one-year limited warranty; whichever is longer.  
4. What is not covered by this limited warranty?  
This limited warranty does not cover:  
PRODUCT that has been subjected to misuse, accident, shipping or other physical damage,  
improper installation, abnormal operation or handling, neglect, inundation, fire, water, or other  
liquid intrusion; or  
PRODUCT that has been damaged due to repair, alteration, or modification by anyone other

Except as provided by applicable law, you assume the risk of loss or damage during transit and

PRODUCT(s) to the service location. The manufacturer will return repaired or replaced PRODUCT  
under this limited warranty to you. Transportation, delivery or handling charges are prepaid. The  
manufacturer assumes no risk for damage or loss of the PRODUCT in transit. If the PRODUCT failure  
is not covered by this limited warranty, or proof of purchase does not meet the terms of this limited

prior to any further repair activity. You must pay for the cost of repair and return shipping costs for  
the repair of products that are not covered by this limited warranty.

Provide your name, complete and correct mailing address, and telephone number.  
7. Other limitations  
This warranty is the complete and exclusive agreement between you and the manufacturer of  
this AT&T branded PRODUCT. It supersedes all other written or oral communications related to  
this PRODUCT. The manufacturer provides no other warranties for this PRODUCT. The warranty

State/Provincial Law rights: This warranty gives you specific legal rights, and you may also have  
other rights which vary from state to state or province to province.  
Limitations: Implied warranties, including those of fitness for a particular purpose and  
merchantability (an unwritten warranty that the PRODUCT is fit for ordinary use) are limited to one  
year from date of purchase. Some states/provinces do not allow limitations on how long an implied  
warranty lasts, so the above limitation may not apply to you. In no event shall the manufacturer  
be liable for any indirect, special, incidental, consequential, or similar damages (including, but not  
limited to lost profits or revenue, inability to use the PRODUCT or other associated equipment, the  
cost of substitute equipment, and claims by third parties) resulting from the use of this PRODUCT.  
Some states/provinces do not allow the exclusion or limitation of incidental or consequential  
damages, so the above limitation or exclusion may not apply to you.  
Please retain your original sales receipt as proof of purchase.

DECT 6.0 digital technology  
The AT&T DECT 6.0 products offer unsurpassed range performance and sound clarity. This is  
achieved through a unique antenna design and advances in noise-filtering technology. An  
independent laboratory has confirmed that AT&T DECT 6.0 products perform up to 45% better in  
range competitions. Now calls can be taken in the basement, backyard and garage with exceptional  
sound quality.  
Telephone operating range  
This cordless telephone operates within the maximum power allowed by the Federal  
Communications Commission (FCC). Even so, this handset and telephone base can communicate  
over only a certain distance — which can vary with the locations of the telephone base and  
handset, the weather, and the construction of your home or office.  
Redefining long range coverage and clarity  
This telephone base comes with an antenna which gives much better clarity and covers a longer  
range than before.
